- No License Key was applied (If this is the case, then use your serial number to retrieve your license keys from our CustomerArea.)
- A License Key was applied but the Computer Name used to generate it does not match the Computer Name of the machine it is running on (applies to Server License Keys)
- A License Key was applied but the version of the key does not match the version of the DLL
